Class LocationProbCalc

java.lang.Object

edu.gsu.cs.dmlab.tracking.LocationProbCalc

All Implemented Interfaces:

ISTLocationProbCal

public class LocationProbCalc
extends Object
implements ISTLocationProbCal

This class is used to calculate the probability of an event at the given location being either the start of a track or the end of a track(enter prob/exit prob). Which one is dependent upon the file it uses as input.
